2.0 REASSEMBLY
HELICOID ASSEMBLY (503)
2.1 Drop the Diaphragm Housing Assembly (527M) in place in the Inner Helicoid (44), and
replace the three screws (53). When correctly inserted, the Diaphragm Lever (109M) on
the Diaphragm Housing Assembly will align with the notch on the front rim of the Inner
Helicoid. The three screws (53) should not be cemented at this stage since a diaphragm
adjustment is to be performed at final assembly (paragraph 2.16).
2.2 Slide the Cam Ring (34) over the Inner Helicoid (44). When correctly assembled, the cam
tracks on the Cam Ring shall cross the cam tracks on the Inner Helicoid.
2.3 Insert the 2nd Lens Group Ring (40) in the Inner Helicoid (44) with the internal threads
towards the front of the lens, and replace three sets of Roller Shaft (43), Roller A (42),
Roller B (41) and Washer (10). The correct position of the rollers is shown in Figure 2.
It is advisable to replace the old Washer (10) with a new washer at reassembly.
